PUIVIPING-ENGINE.

SPECIFICATION forming part of Letters Patent No. 715,1 31, datedDecember 2, 1902. Application i166 May 6, 1902. sel-a1 No. 106,161. (Nomaar.)

To zr/ZZ whom, t may concern,.-

Be it-known that I, FRANCIS LEONARD ORR, residing at Thurman, in thecounty of Fremont and State of Iowa, have invented a new and ImprovedPumping-Engine, of which the following is a specification.

My invention relates to improvements in that type of liquid-elevatingmeans operating under an explosive and a vacuum energy created by thecombustion of the explosive mixture and in which after being started theoperation will continue so long as the Working agent is fed thereto; andthe same primarily seeks to provide a pumping means or engine of thecharacter stated of a simple, effective, and economical construction andin which the operation can be conveniently controlled.

In its generic nature my invention comprehends a casing, a supplementalcylinder Within the casing and in communication therewith, a liquidinlet and ofttake for the casing, an explosion-chamber having a valvedexhaust through Which the exploded gases pass to the supplementalcylinder for creating a vacuum Within the casing, and a novelcooperative arrangement of automaticallyoperating valves and electricclosing means controlled by the rise and fall of the fluid drawn Withinthe casing by the intermittent vacuum operations.

In its more complete make-up this invention includes a combinedair-supply-regulating valve and spark-circuit controller, aclosure-valve for the luid-offtake, a float for cooperating With saidcombined valve and circuit-controller; and in its still more subordinatefeatures this invention consists in certain novel details ofconstruction and peculiar combination of parts, all of Which Willhereinafter be fully described and specifically pointed out in theappended claims, reference being had to the accompanying drawings, inwhich- Figure 1 is a vertical section of my explosive-engine pump, theelectric igniting means being diagrammatically represented and theseveral parts shown in position for igniting a charge of the Workingagent for expelling the air and to create a vacuum Within thepump-casing. Fig. 2 is a similar view illustrating a charge of Waterdrawn Sinto the casing by a Whole or partial vacuum therein,

the float-valve being shown in a position for opening theoHtake-controlling valve and airinlet and for moving theigniting-circuit controller or switch in its open position. Fig. 3 is ahorizontal section on the line 3 3 of Fig. 2.

In the practical construction myinvention comprises an outer casing 5 ofsuitable size and shape, preferably cylindrical, the lower end of whichhas a threaded tap 5 for connecting with the Water lift or feed pipe 1,and adjacent the threaded tap 5' it has a second threaded tap or boss5b, to which the outlet or oftake pipe joins, as clearly shown.

At the upper end the casing 5 has two or more outlets 5c surrounding acentral opening 5d, to which the combustion-chamber 12 connects, and thesaid openings 5c are normally closed by a disk, of rubber, leather, orother suitable material, protected by a spherical metal guide 9,perforated to give quick relief to the movement of the disk 8, forreasons hereinafter explained.

The opening 5d to the combustion-chamber is normally closed by aspring-held valve 13, operating in a valve-cage 13a, located in theupper end of an internal or supplemental cylinder 6, closed at the topfrom the casing 5,

Vbut open at the bottom and in communication with the said casing 5, theparts being arranged to provide for communication between theexplosion-chamber 12 and the casing 5 through the internal cylinder 6,for reasons hereinafter set forth. t

11 designates an insulated plug that fits into the combustion-chamber 12and carries the terminals 11iL 11 of the igniting-circuit, whichterminals to insure a positive ignition of the working agent at theproper time are disposed adjacent the intake 10, provided with aback-check valve 22, as clearly shown. The intake 10 in practice isprovided with a suitable source of supply with the working agent,(explosive mixture,) the feed of which may be cut off by valve 10,located at any point in the pipe 10.

Near the upper end the inner cylinder 6 has an air-intake that projectsthrough the outer casing 5, the entrant end 7a of Which is constem 7b ispivotally connected to one arm of the bell-crank lever 18, fulcrumed at18'L1 at a point diametrically opposite to a pair of contact-plates 1616a of the electric-current-controlling means, which includes acircuit-closing head 18b on the outer end of the lever 18, as best shownin Fig. 4.

15 indicates a battery, and 14 an inductioncoil, forming a part oftheigniting means and of the ordinary construction.

2 designates al gravity fluid-pressure valve for closing oif thelift-pipe l, and 2a a cage for the said valve.

2l designates a vertical stem secured at the upper end to-the valve-cage13a and at the lower end to the valve-cage 2a, and 2O indicates the stemof the offtake-closing valve 3, connected at the upper end to the longarm of the lever 18. A float 17 is held to slide upon the rod 2l, andthe said iioat includes a tubular pendent extension 17a, adapted toengage with a laterally-extending member 23,

xedly joined with the stem 2O of the valve 3.

The manner in which my engine-pump operates is best explained asfollows: Assuming the parts to be in the position shown in Fig. 1 and acharge of air to be within the casing 5 and a working-agent charge to becollecting Within the combustion-chamber 12, when the said charge is ofsufficient pressure it is ignited and the explosive force pushes backthe valve 13 and allows the exploded mixture to pass into the cylinder6, which mixture forces out the air within the cylinder and casing inthe direction indicated by the arrow and out through the openings 5c toatmosphere, the disk valve 8 at this time being forced open by pressurewithin the casing 5.

The air within the casing 5 being exhausted,-

a vacuum is created within the casing 5, and by reason thereof the wateris drawn up the lift-pipe and the valve 2 raised thereby to permit thewater flowing into and filling the casing 5. As the water fills into thecasing 5 the float 17 rises until its extension 17b engages with thelever 18, and in so doing the electric igniting-circuit is broken, andat the same time the valve 3 to the offtake is open, and the valve 7X,that controls the air-inlet in the casing 5, is also open, therebyallowing the atmospheric pressure to force out the water charge drawninto the casing' 5 by the prior vacuum energy through the outlet-pipe,it being understood that in practice the lever 18, and its connectionscontrolled thereby, is held in the position to which it was shifted bythe Hoat 17, and thereby keeps the valve 3 open until the water withinthe casing is practically exhausted, or at least to a point below thelower edge of the inner cylinder 6. At this time'the oat 17 indescending engages the member 23 and forces the valve 3 to its closedposition, the valve 2 at this time being held closed by the water belowit and its own gravity, it being also understood that as the floatengages the member 23 and pulls down on the stem 20 the lever 18 will beshifted back-to its rst position, with its head 181 contacting with theplates 16a 16a to again close off the igniting-circuit, and with thevalve 7 to close off air from the inner cylinder 6, the spring action onthe valve 13 during the aforesaid operation closing thecombustion-chamber from the cylinder 6 and holding in a new charge ofworking agent. After the parts again assume the position shown in Fig. 1a new charge is exploded in the chamber l2, and the operation of thepump is repeated as before, and which operation continues so long as theworkingag'ent feed is permitted to flow into the combustion-chamber 12.

While the special arrangement of parts shown in the drawings clearlyillustrate my invention, yet it will be understood that the saidarrangement, particularly the details of construction, may be varied ormodified without departing from the principler of my invention or thescope of the appended claims.
